The correct answer is D. All producing sectors of the economy.
Intermediate consumption is the value of goods and services used up in the production of other goods and services. It includes the cost of raw materials, energy, and other inputs used in the production process.
All producing sectors of the economy demand intermediate consumption. This is because all businesses need to use inputs to produce their goods and services. For example, a car manufacturer needs to use steel, rubber, and other materials to produce cars. A restaurant needs to use food, labor, and other inputs to produce meals.
The demand for intermediate consumption is determined by the level of economic activity. When the economy is growing, businesses need more inputs to produce more goods and services. This increases the demand for intermediate consumption. When the economy is shrinking, businesses need fewer inputs to produce fewer goods and services. This decreases the demand for intermediate consumption.
The demand for intermediate consumption is also affected by the prices of inputs. When the prices of inputs rise, businesses need to spend more on inputs to produce the same amount of goods and services. This increases the demand for intermediate consumption. When the prices of inputs fall, businesses need to spend less on inputs to produce the same amount of goods and services. This decreases the demand for intermediate consumption.
